通勤可达范围的居住区分类及特征指标

Analysis on Characteristic Indexes and Classification of Residential Districts Based on 30minute Accessible Commute Range

摘要:

以上海市15个居住区通勤出行调查数据为基础，确定合理的单次通勤出行时间预算目标值为30 min.利用电子地图应用程序编程接口(API)二次开发和地理信息系统(GIS)技术绘制居住区居民使用小汽车、轨道交通、常规公交方式30 min通勤活动空间可达范围.从30 min通勤可达范围交通系统配置角度，分析居住区通勤可达范围差异产生原因.重点对居住区公共交通30 min通勤可达范围内各类提供工作岗位的设施点密度、被调查者上班地点落在该范围比例、使用小汽车通勤出行比例之间的相关性进行分析.提出分类居住区的针对性交通改善策略.

Abstract:

Based on the commute survey data of 15 residential districts, this paper determined a reasonable budget value of single commute travel time was 30 minutes. Then 30minute accessible commute range of respectively using car, railway and bus based on secondarydeveloped electronic map API(application programming interface) and geographic information system(GIS) technology was depicted. From the traffic system configuration in 30minute accessible commute range, the reason for the difference of accessible commute range was analyzed. Correlation among density of various facilities providing working post, the proportion of respondent workplace and the ratio of using car for commute in 30minute accessible commute range was specially analyzed. Finally, traffic improvement strategy of classified residential districts was proposed.
